Here is latest Master code. This has another function in that it tells you which cell is highest/lowest as well as what voltage they are.

I have also removed the extra Alarm code I put in yesterday and test drive was fine. So it will now give an alarm the first time an error occurs rather than waiting for an error to occur a number of times before triggering.
Three more pics.
One on the move
